The lube question is somewhat subjective and can be dependent to some extent on what internals you have (per Vince's comments) and what your goals are with the lube regime (e.g. longevity between applications / cleaning, power efficiency... less spring, power reduction... spring damping, consistency through temperature extremes, reduced twang / noise and others...)
A bit like pizza toppings, endless variables and choice but, one persons favorite may not be yours!.
